How Can I Remove Points From A Matplotlib Plot Before Plotting A New One?

I am trying to plot a point whose position is controlled by a slider. However, each time the slider is moved a new point is plotted without deleting the old one. How do you remove

Solution 1:

You can change the properties of point:

def on_change(val):
    point.set_offsets([x[int(val) / 1], y[int(val) / 1]])
    point.set_3d_properties([z[int(val) / 1]], "z")
    fig.canvas.draw()
